http://en.wikipedia.org/wiki/Lunar_distance_%28navigation%29
I have made a major rewrite, partly from Paul's suggestions, partly from the
not-half-bad summary of lunars in the article on Celestial Navigation
(http://en.wikipedia.org/wiki/Celestial_navigation#Lunar_distance), and
partly from my own ideas. Sorry about that last part. I don't know when
the Nautical Almanac added the planets to the lunar distance tables, but I
am certain George can get back to us after he completes his article for
"Navigation News".
I struck out the "Theory" section and subsumed the "practice" section into
the "Method" introductory paragraph.
I think Wikipedia now has the bare bones of a decent article.
We can leave it as-is and suggest further outside-of-wikipedia reading on
the subject (web pages AND books).
Or we can add as much information as all of you lunar experts can supply.
Explain the size of the error introduced if parallax is not corrected for.
Define "clearing". Describe (in 100 words or less) the difference between
the method of lunar distance, as originally presented by Maskeleyne, and the
"new lunars" recently discussed on this list. Fill in useful bits of
history (cross-reference the longitude article whenever possible). Add
citations (just place them in-line -- citation experts will rush in to turn
them into footnotes). If you how an encyclopedia article is supposed to
turn out, you get the gist of the style guidelines. Just typing in some
text is easy. You don't even have to create an account.
